Delivery: Very well packed and fast shipping. Very competitive shipping cost ($US100 to New Zealand) and about $800 cost here. Quality: Good robust units, that so far work reasonably well. Design: Ubiquitous design that seems to do what is required. A lot of similar units in New Zealand with new labels sell for twice what I paid Service: Very good and quick communication, some problems with translation but overall surprisingly good. The whole experience was let down by very poor and incorrect instruction manuals - they were for different models and I still have been unable to obtain the correct manuals. For some people that may not be a problem, but I have been out of the trade for 20 years, so these units are new to me
